TECHNICAL FIELD

This invention is related to offering of a training device for avoidingthrombophlebitis known as economy syndrome in case of being obliged tokeep seated position for long time in airplanes and so on.

BACKGROUND TECHNOLOGY

In the case of disorders where someone has a disability as a result ofhemiparesis after apoplexy, a decline of muscular strength of the lowerextremities is caused by the rupture of the Achilles' tendon and/ordisabilities of the range of motion in the joint of a leg or kneeoriginating in a bone fracture of the lower extremities and otherconditions if left untreated, an ankle or knee becomes a contracture andchronic disabilities of the lower extremities have been originated.

Therefore, these functional disorders become the training or exercisefor the needed recovery.

Also, in case of being obliged to keep seated for long time and noexercises can be performed, it is subject to thrombophelebitis known aseconomy syndrome.

As its solution, it is common to show a video of the lower limb exerciseand to ask passengers to perform it.

However, since its effect of the training with no equipment is limited,more effective training device is needed.

This exercise concept, which was named “JIKOTADOUUNDOU” by the researchof this application inventor and the others, is proposing to theexisting rehabilitation medicine and is decided the “MOTIVATIVE”exercise as an English notation and papers were presented at academies.

It is a tentative name from the Japanese word “JIKOTADOUUNDOU”.

For example, exercise and/or training corresponding to the muscularstrength of a disabled person become necessary in order to rehabilitatea decline in the function of the lower extremities and disabilities ofthe range of motion in the joints of legs or knees.

Hereon, for example in the intension of the lower extremities' musclethe plantar flexion exercise causes the foot tip to be inflected to thereverse side from the ankle shrinking the quadriceps, extending theanterior tibial muscle and shrinking the gastrocnemial muscle andAchilles' tendon and dorsiflexion exercise causes the foot tip to beinflected upwards towards the ankle extending the quadriceps, shrinkingthe anterior tibial muscle and extending the gastrocnemial muscle andthe Achilles' tendon.

In the case that there is no ability to exercise oneself, thedorsiflexion and plantar flexion exercise mentioned were performed as astretch exercise by the movement of the other persons power as a passiveexercises by a physical therapist or another person.

There was the Dorsi-Plantar Flexion exercise device of the model utilityright U.S. Pat. No. 2,004,587 for the plantar flexion and dorsiflexionexercise of the ankle and knee in order to rehabilitate a disabledperson who is able to maintain the sitting position with subjectivemuscular strength for doing those exercises.

There was the Dorsi-Plantar Flexion exercise device of the design Pat.No. 997,739 for the plantar flexion and dorsiflexion exercise of theankle and knee in order to rehabilitate a disabled person who is able tomaintain the sitting position with subjective muscular strength fordoing those exercises.

The Dorsi-Plantar Flexion training devices can perform the motivativeexercise any time at one's convenience.

By the way, the Dorsi-Plantar Flexion exercise device of the modelutility right No. 2,004,587 has adapted means to move several propercasters and rotate freely under a foot rest bar that keeps both feet onit and also has adapted securing tools to keep the feet on the uppersurface of the foot rest bar and to allow the feet to detach freely.

Also, a lower extremities function training device of design Pat. No.997,739 has adapted the means that has a spring under a foot rest barand it is possible for both feet to be kept on and to detach freely onthe upper surface of the foot rest bar.

However, in the case of a disabled person who prepares the above patentsfor the home training plantar flexion and dorsiflexion exercises withtheir own personal intention, the Dorsi-Plantar Flexion training deviceand the lower limb function training device exerted the opposite effectsometimes due to exercising as much as he or she can do while expectingearly recovery.

Also in the cases that a director or caregiver are not close by, thedisabled person who does not keep the caregivers instruction of theexercise repetitions and exceeds the equivalent range of the suitedexercise by many times will not achieve the expected improvement.

Although, muscular-strength reinforcement became the purpose of trainingto the disabled person with whom the improvement progressed, a load isnot applied at the time of exercises and it was not able to be used formuscular-strength reinforcement.

In the same time the heavily disabled person could not move theDorsi-Plantar Flexion exercise device of the model utility right Pat.No. 2,004,587, a device of motionlessness condition, by a subjectivemovement of lower extremities of his or her own healthy side.

The Dorsi-Plantar Flexion exercise device of the model utility rightPat. No. 2,004,587 was not used widely.

The previous invention described above is for patients to performMOTIVATIVE exercise

The invention provide for people on airplanes, buses to move longdistance and/or patients in the hospital for avoiding thrombophlebitisknown as economy syndrome.

The invention is used to solve the subjects mentioned above and to aimat offering a lower limb function training device, which can preventthrombophlebitis known as economy syndrome.

And it is the secondary purpose to offer a lower limb function trainingdevice, which can perform two kinds of exercises.

And also, it aims to offer a lower limb function training device, whichcan motivate people to exercise and enables exercise two kind ofmovement.

There is no report that economy syndrome went out even if airlines haveintroduced the exercise by stretching legs and the Dorsi-Plantar Flexionexercise with no equipment.

A lower limb function training device provides two kinds of exercises.

One is a Dorsi-Plantar Flexion exercise device and the other is astretch exercise.

People can use it as a Dorsi-Plantar Flexion exercise device by puttingtoes on the device with heels on the ground surface and can do abilateral movement in one time training.

People can use it as a stretch exercise device by putting sole of feetand/or heels on the device not to touch those the ground surface and cando a bilateral movement in one time training.

If the symptoms progress, it may become pale by compression of arterialblood flow. Also, it may cause thrombophlebitis of lower limb.

Moreover, if thrombus which caused this venous inflammation lodges inpulmonary artery, it may lead the sudden death because of the pulmonaryembolism.

The news that a Japanese famous soccer player was hospitalized becauseof the pulmonary embolism and the venous inflammation is well known. Hereceived a medical treatment to dislodge the thrombus by administrationof anticoagulant drugs.

This invention, training with the device, enables to give stimulus thatcould not be obtained from the exercise with no device and improves theflow of the vein even if it is obliged to keep seated for long time.Moreover, this will prevent and avoid the risks mentioned above.

DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

I explain the first embodiment of a lower limb function training devicein this invention by using FIG. 1 and FIG. 8.

FIG. 1 is a perspective view of a lower limb function training device ofthe first embodiment.

FIG. 2 is a front view of FIG. 1.

FIG. 8 is a flowchart in case, which the connection between a wheel anda motor are cut.

Furthermore, the drawing of a rear wheel support of a right and leftpart is omitted in FIG. 2.

Also, the drawing of the front wheel support parts is omitted in FIG. 3.

A foot rest bar (1) is formed with wood in midair with a planeabbreviation rectangular (when necessary another material can be used inplace of wood, such as plastic).

The foot rest bar (1) is having an area of sufficient width that can putboth feet (51 a, 51 b) (for example, the size of the side from approx 20cm to approx 25 cm, length).

Therefore, a disabled person can set both feet (51 a) and (51 b); a foot(51 a) with disability, which has hemiparesis of lower extremities of anerve, decline of the lower limbs extremities muscular strength thatoriginates from a plasmotomy of Achilles' tendon K of any of the lowerextremities, a disability of a range of motion, etc. of an ankle (ro),and also a knee (i) of any bone fracture etc. and a foot (51 b) of theother healthy foot without any disability in the condition of sitting ona chair.

A slip stopper (1 a) assembles in the upper surface of a foot rest bar(1) if needed.

The slip stopper (1 a) is formed by pasting up the rubber sheet, forexample, when a foot rest bar (1) is formed by plastic etc., it can beformed in the upper surface of a foot rest bar (1) at one.

Although a foot rest bar (1) is a hollow structure, if an informationtransmission route (14) can be assembled that is composed of electricwire etc, within the hollow space.

A heel support part (4), which is formed by belt like straps, such asplastic, skin and cloth, for example, is almost shaped like a letter Cshown in a plane view and then is fixed with tack wear, nail wear,screw, etc. impedes a movement to the rear of the heel of two feet (51a, 51 b) if the two feet (51 a, 51 b) keep on the surface of a foot restbar (1).

Furthermore, in the case that the heel support part (4) is formed fromplastic, it may form a unit to a foot rest bar (1).

And also, a setting band (3) that the edge department of the right andleft was adhered to a foot rest bar (1) is set up both with the intervalfrom this heel support part (4) to the front and in the omission centralposition of the long hand direction of a foot rest bar (1).

A setting band (3) is adhered to under the surface of a foot rest bar(1) as for the center, both end parts which pass the plane Japaneseletter character form conducive brackets (2 a,2 b) respectively thatassemble in each right and left aspect of a foot rest bar (1) of eachand are keeping upward of a foot rest bar (1).

And both right and left end parts (3 a, 3 b) of band setting band (3)are overlapped mutually and are engaged by a proper engaging means suchas a velvet fastener, snapshot, hook, etc easily.

However, the setting band (3) is composed of one setting band, it isavailable to compose of two setting bands, the end parts of which arefixed in a foot rest bar (1).

The setting band (3), which covers insteps of both feet (51 a, 51 b)from upper side is impeding the movement of both feet (51 a, 51 b) fromthe upper and front side.

Securing tools (3,4) that hold both feet (51 a, 51 b) in a foot rest bar(1) are composed by the heel support part (4) and the setting band (3).

The structure, material, etc. of securing tools (3,4) are possible tochange suitably if both feet (51 a, 51 b) can be kept and set on a footrest bar (1).

Furthermore, at the condition that a patient recovered and strength ofeach foot can be applied to both legs, securing tools (3,4) to both legsmay be unnecessary.

Rear wheel support parts (5, 6) that freely rotate horizontally around acenter perpendicular axis (8) are attached to each side, right and leftat the lower back part of the foot rest bar (1).

And a left side rear wheel (9) is attached and rolls freely on a wheelsupport part (5) on the left side and the speed sensor (16) as amovement speed detection device that detects the rolling speed of therear wheel (9) and brake (17) as a brake device that brakes the rotationof the left side rear wheel (9) assembly.

A right side rear wheel (9) is attached and rolls freely on a wheelsupport part (6) on the right side and a number-of-times sensor (18), around-trip movement number sensing device, that detects the number ofround trip movements of the rear wheel (9) and brake (17) a brake devicethat brakes a rotation of the right side rear wheel (9) assembly.

Although, the rear wheels (9) move in a cross direction while rollingand are also capable of moving around while inclining right and/or leftin a cross direction due to the rear wheel support parts (5,6) pivotingright and/or left.

The wheel support parts (5,6) are regulated in range (for example,approx 10 degrees right and left in both directions) and are not able tomove in a side-to-side direction.

Also, a front wheel support part (7) is attached to the front lower partof the foot rest bar (1) and pivots freely around a center perpendicularaxis (8).

The right and left front wheels (11) are attached to a front wheelsupport part (7) and roll freely with a motor (19) that drives the frontwheels (11) and a brake (17) as a brake device that brakes a rotation ofthe front wheel (11) assembly.

Front wheels (11) move around a cross direction while inclining rightand left due to the front wheel support part (7) pivoting right andleft; same as the rear wheels (9).

The front wheel support part (7) is regulated in range (for example,approx 10 degrees right and left in both directions) and are not able tomove in a side-to-side direction.

Thus, this explains the reason for pivoting of the front wheels (11) andrear wheels (9) that were regulated in the condition that a side-to-sidemotion is directed.

This lower limb function training device needs to restrict the movementof a side-to-side direction in order to detect an exercise of crossdirection and to use the data.

However, the forward direction of an exercise tends to deflect, in thesame direction, of a foot (51 a) with a disability because of the powerof another healthy foot (51 b) without any disability is strong due tosetting both a foot (51 a) with a disability and another healthy foot(51 b) without a disability.

In this case, it becomes a corrective exercise instead of a naturalexercise by readjusting to move completely straight, and then thecontinuation of training and exercise might be difficult due to bigloads applied to a foot (51 a) with a disability.

Thereupon, this regulates the right and left pivoting movement angles ofthe front (11) and rear wheels (9) that can move crosswise in a linewith an angle of about 10 degrees right and left from center, the middleempirically in order that the difficulty of continuation of suchtraining and exercise are eliminated.

Furthermore, when the training leader admits necessity and a correctiveexercise (the body parts that cause abnormality by becoming contractureis corrected by exercise) is necessary, it is possible to use acorrective exercise due to making wheels (11,9) impossible to pivot inthe side-to-side direction and move only as a fixed wheel which movesonly in the cross direction of order.

And, a control unit (20) that is composed of a microcomputer etc.attaches to a lower limb function training device and a speed sensor(16) and also a number-of-times sensor (18), are connected to the inputend through an information transmission route (14), on the other hand, abrake (17), a motor (19) and an output device (91) are connected throughan information transmission route (14) on the side output.

Furthermore, an output device (91) is not necessarily needed toassemble; detecting values of a speed sensor (16) and a number-of-timessensor (18) can be placed in the outside by this output device (91).

A speed sensor (16) detects turning speed of rear wheels (9) in otherwords the movement speed of a foot rest bar (1).

Although, a foot rest bar (1) reciprocates and the direction of movementis changed alternately, speed sensor (16) is outputting the absolutevalue of the movement speed of the foot rest bar (1).

A timer (20 a) is built in the control unit (20), and the average valuefor every interval of detected speed (for instance, each specified timeand the movement of a foot rest bar (1) during forward movement) by thespeed sensor (16) can be computed.

Furthermore, the lowest value of the mean value of movement speed of afoot rest bar (1) can be set up by a speed setting switch (5 b) to thecontrol unit (20).

Also, the maximum value of the reciprocating movement of a foot rest bar(1) can be set up to control unit (20) by a reciprocating motionssetting (6 b).

According to condition of a patient, an increment of 5 cm from the speedof 5 cm a second to the speed of 30 cm a second and that an increment of10 cm from the speed of 30 cm a second to the speed to of 50 cm a secondcan be set up by a speed setting switch (5 b) to the control unit (20).

And, a control unit (20) actuates all brakes (17) breaking andsuspending the rear wheels (9) and front wheels (11) in the case thatthe average speed that is calculated with control unit (20) fell belowthe speed that was set up by a speed setting switch (5 b).

And, it is not possible to exercise once again, because the brakes (17)are not disarmed if a release switch (7 i) is not operated.

Number-of-times sensor (18) that detects the number of the reciprocatingmovement of a rear wheel (9) in other words the number of thereciprocating movements of a foot rest bar (1) outputs the detectednumber to the control unit (20).

This control unit (20) actuates all the brakes (17) breaking andsuspending the rear wheel (9) and front wheel (11) in the case thatdetecting value of number-of-times sensor (18) reaches a set value ofreciprocating motion setting (6 b) by comparing the number of thereciprocating movements from number-of-times sensor (18) to the valuethat is set.

And, it is not possible to do an exercise once again, because the brake(17) is not disarmed if a release switch (7 i) is not operated.

An exercise number that should be accomplished for each increment of 10times, a standard from 10 times minimum to 50 times maximum is set bythe reciprocating motion setting (6 b) to the control unit (20).

Furthermore, the arrangement and structure of the parts of a controlunit that make it possible to induce a proper change can arrange speedsensor (16) and a number-of-times sensor (18) with mixed loading to thesame unit

A power switch (7 b), a coercive speed setting switch (7 f), a coercivesetting reciprocating motion switch (7 j), an addition resistivitycontrol switch (7 e) and a release switch (7 i) for all of controlreleasing are assembled in a front wheel support part (7).

A lower limb function training device of the first embodiment has thefunction as an assistive passive exercise device due to assembling abattery storage part (7 c) as a battery, a load device of a front wheel(11) and a motor (19) as a drive unit in a front wheel support part (7).

The speed in increments of 5 cm from the minimum speed of 5 cm a secondto the maximum speed of 30 cm a second set up by a coercive speedsetting switch (7 f) and also a number of the reciprocating movements ofa foot rest bar (1) for each standard increment of 10 times, from aminimum 10 times to a maximum 50 times is set up by a coercivereciprocating motion setting switch (7 j) to the control unit (20).

Then, the control unit (20) drives the motor (19) and makes a foot restbar (1) reciprocate at a set speed and makes a foot rest bar (1) suspendby motor (19) suspending at the number of reciprocating movements becomea set value.

Thus, we can make patients exercise automatically.

Furthermore, a connection has cut the transmission system between motor(19) and front wheel (11) with a clutch. and the load of motor (19) isnot transmitted in the case that motivative exercise is done.

Even the power source of the others such as the engine is good, althougha drive unit is a motor (19).

Also a battery storage part (7 c) serves to be used by the battery orother power supplies that are sufficient as a battery.

In the case that training is started from the condition withoutresistivity and the necessity to load for training is recognized due tothe improvement of a patient function is seen, control unit (20) loads aresistivity that as a load etc. is born from the turn of motor (19) onthe basis of this set value to the front wheel (11) due to the set up ofincrements 0.5 kg from 0.5 kg to 2.5 kg is available with an additionalresistivity control switch (7 e) to the control unit (20).

For example in the case that there are hemiparesis after apoplexy, adecline of muscular strength of the lower extremities is caused by therupture of the Achilles' tendon (K) and/or disabilities in the range ofmotion of ankle (ro) originating in a bone fracture of the lowerextremities, both feet (51 a, 51 b) are set and fixed in a foot rest bar(1) by setting together the Heels (A1) of both foot (51 a) and foot (51b), foot (51 a) with disability and another healthy foot (51 b) withoutany disability to heel support part (4) and attaching foot tip (A2) bysetting band (3) strapping both feet (51 a, 51 b), fitted in the sittingposition because of the first embodiment of lower limb function trainingdevice is composed like this (Refer to full line and also dashed line ofFIG. 5).

Thus, it is easily able to set and put on both feet (51 a, 51 b) withthe upper surface of a foot rest bar (1) corresponding to the size of adisabled person's feet, because it is good that [the]

Herewith, the training and also bending and stretching exercises of knee(i) and flexion and dorsiflexion of ankle (ro) are done from solid lineand also dashed line of FIG. 2 due to making a foot rest bar (1) move ina cross direction horizontally with wheels (9,11) rotated by graduallyadding power while controlling subjective movement and making lowerextremities extend and contract and muscular strength of lowerextremities reinforce and also expand a range of motion of ankle (ro) inorder that foot (51 b) without any disability assist foot (51 a) with adisability by not increasing a burden.

In other words, in the case that a foot rest bar (1) that sets and fixesboth feet (51 a, 51 b) move forward as drawing of FIG. 6 knee (i) opensfrom almost 90 degrees and extends, quadriceps (L) as lower extremitiesmuscles shrink, the anterior tibial muscle (M) extends, both thegastrocnemial muscle (N) and Achilles' tendon (K) shrink and ankle (ro)flexes to plantar Flexion.

In the case that a foot rest bar (1) moves in a cross direction byexpansion and contraction of both knee (i) and ankle (ro), so that theburden of both feet (51 a, 51 b) decreases due to no side vibration butstable transfer and both feet (51 a, 51 b) tightened with the settingband (3) and heel support part (4) as a means to hold are held on a footrest bar (1) and also a slip stopper (1 a) assembly on a foot rest bar(1), both feet (51 a, 51 b) do not slip on a foot rest bar (1) but movewith a foot rest bar (1).

Although effect of the exercises mentioned are conducive to improvedisabilities, the number of the exercise performed (step 3) will stopautomatically (step 5) and it is conducive to improvement ofdisabilities due to the number of exercises detected withnumber-of-times sensor (18) (step 1 of FIG. 8) and also the number ofexercises that should be performed is previously set up to 10 times as aminimum and 50 times as a maximum in order that the disabled persons whohave a desire to recover early as possible and who do exercisesexceeding the equivalent range, which exceed exercises best suited tothem, will not get the expected improvement or is nonexistent.

Although there is a difference in the speed of movement for everyperson, usually speed decreases due to fatigue from a constant speed atthe time of use.

Thereupon, it is conducive to improve disabilities, in the case that thedetected movement speed of a foot rest bar (1) with speed sensor (16)(step 2) and the average speed are detected under setting speed (step 4)by setting up an increment of 5 cm in the minimum range 5 cm a second tothe maximum speed of 30 cm a second to the control unit (20) previously,that it stops by the work of a brake system in accordance with judgingfatigue.

The range of users spread more and more and a high effect is obtainedbecause when necessity is admitted for training to adding resistivityfor exercise and starting from the condition without resistivity andimprovement has been seen in the function of a patient, addingresistivity in increments of 0.5 kg from 0.5 kg to 2.5 kg of loadresistivity that are borne from the turn of motor (19) by an additionresistivity control switch (7 e) to an axle (11) is available.

Furthermore utility of it rose remarkably by having the devicesalternate functions as a passive exercise in the case that heavilydisabled persons cannot move the device and motionlessness conditions ofthe lower extremities of the healthy side cannot perform the motivativeexercise because it functions as an assistive passive exercise deviceand was given due to an exercise performed automatically at the speed of5 cm increments from the speed of 30 cm a second to a speed of 5 cm asecond with the minimum that was set up with a coercive speed set switch(7 f) and a control unit that stops by itself within the designatednumber of times that is set up at increments of 10 from the minimum of10 times, to the maximum of 50 times with a coercive reciprocatingmotion setting switch (7 j) being set up.

Next, I explain the second embodiment by using FIG. 9 to FIG. 13.

FIG. 9 is a perspective view of a foot rest bar of the secondembodiment.

FIG. 10 is a perspective view of a foot rest bar move stand of thesecond embodiment.

FIG. 11 is a perspective view of the second embodiment.

FIG. 12 is a side view of the second embodiment.

FIG. 13 is a perspective view of the second embodiment in a usage state.

Furthermore, I omit the detailed explanation of composition elementsparity to the first embodiment by putting the same mark in theexplanation of the second embodiment.

The second embodiment consists of a foot rest bar (1) and a foot restbar cart (22) as a measuring instrument, and the similar functions tothe first embodiment are realized by combining a foot rest bar (1) and afoot rest bar cart (22).

Same as the first embodiment, both a heel support part (4) and settingband (3) assemble a foot rest bar (1) of this embodiment.

Several wheels (21) that may move toward the right and left freelyassemble an undersurface of a foot rest bar (1).

The lower limb function training device needs to restrict the movementin the right-and-left direction in order to detect the movement in across direction.

However, same as the first embodiment, the progression of an exercisetends to deflect the foot (51 a) with a disability because of thestrength of another healthy foot (51 b) without any disability is strongdue to setting both a foot (51 a) with disability and another healthyfoot (51 b) without any disability.

In this case, it becomes a corrective exercise instead of a naturalexercise by readjusting to move forward completely, and then thecontinuation of training and exercise might be difficult due to bigloads applied to foot (51 a) with disability.

Thereupon, wheels (21), which roll side-to-side, assemble on a foot restbar (1) in order to eliminate the difficulty of the continuation of suchtraining and exercise.

And, two pieces of the front side wheel (21) assemble and install in awheel bearing (23 a) on the front side of a foot rest bar cart (22), andtwo pieces of the rear side wheel (21) assemble and install in a wheelbearing (23 b) on the front side of a foot rest bar cart (22).

The number of wheels (21) selection is available, if it is effective tomove right and left.

The embodiment can be used as a corrective exercise when a trainingleader admits and a corrective exercise is necessarily needed.

A foot rest bar cart (22) consists of a box unit (22 a), a top surfacewhich is opened, wheel bearings (23 a, 23 b), a movable belt (24) withinfinite form to cross direction movement, to which wheel bearings (23a, 23 b) assemble, a derivation roller (25 b) that guides the movablebelt (24) and is supported to a box unit (22 a) with a driving roller(25 a) that drives the movable belt (24) and is supported to a box unit(22 a) with available rotation, a speed sensor (26) (Parity to a speedsensor (16) of the first embodiment) as movement speed detection device,a number-of-times detection sensor (27) (Parity to a number-of-timessensor (18) of the first embodiment) as a round-trip movement numbersensing device, a movable belt brake roller (28 a), a brake (28) (Parityto a brake (17) of the first embodiment), a motor (29) (Parity to amotor (19) of the first embodiment) as a drive unit, a power switch (29a), an addition resistivity control switch (29 b) (Parity to an additionresistivity control switch (7 e) of the first embodiment), a coercivemovement speed setting switch (30 a) (Parity to a coercive movementspeed setting switch (7 f) of the first embodiment), a coercivereciprocating motion setting switch (31 a) (Parity to a coercive settingreciprocating motion switch (7 j) of the first embodiment), a speedsetting switch (32 a) (Parity to a speed setting switch (5 b) of thefirst embodiment), an output device (32 b), a reciprocating motionsetting (33 a) (Parity to a reciprocating motion setting (6 b) of thefirst embodiment), a reciprocating motion output device (33 b), abattery set part (34), a release switch (34 a) (Parity to a releaseswitch (7 i) of the first embodiment) for all of control releasing,external power terminal (34 b), an information transmission route (35)(Parity to an information transmission route (14) of the firstembodiment) and control unit (20).

Furthermore, every part of the second embodiment effects similar processof parity parts of the first embodiment and details of process areomitted.

Although a box unit (22 a) is made of plastic, however, wood or metalare substitutes, in which the part such as rollers (25) assemble inside,and any material of sufficient strength that is possible to protect theinside on the occasion of movement and application, is released withoutcovering the upper part that is similar to a rectangle, is formedapproximately to the height of 30 centimeters, 60 centimeters to theright and left, 1 meter long and is accommodated with a measuringinstrument inside.

A movable belt (24) is composed with twelve movable belt derivationrollers (25 b) and a movable belt driving roller (25 b) to roll freely,makes a foot rest bar (1), which assembles to move in a cross directionhorizontally on wheel bearings (23 a, 23 b) that were established to amovable belt (24) move in a cross direction and foot (51 b) without anydisability reinforce a foot (51 a) with a disability by making lowerextremities bend and stretch like the first embodiment, trains and alsoexercises knee (i) extension and ankle (ro) flexion and dorsiflexion byexpanding a range of motion of knee (i) and ankle (ro)

A motivative exercise, assistive-passive exercise and a resistiveexercise are realized.

A movable belt (24), which has durability, is formed with material thatmoves freely by movable belt derivation roller (25 b) and movable beltdriving roller (25 a) by rolling.

Also, a brake roller (28 a) contacts a movable belt (24) and is made tostop for braking, although, ordinarily, it is not contacting a movablebelt (24).

A drive unit may be connected with a metallic chain structure, althougha movable belt (24) is a synthetic fiber, which is weaved of metal.

Also, a movable belt (24) is good or any material that is transmitted ortransmits rolling to a movable belt derivation roller (25 b) and amovable belt driving roller (25 a) by friction such as leather or fiber.

Twelve derivation rollers (25 b) are assembled and rotate following across direction movement, which is moved by a foot rest bar, of amovable belt (24).

A speed sensor (26) assembles into one of the derivation rollers (25 b)and a number-of-times detection sensor (27) assembles into another oneof the derivation rollers (25 b).

Furthermore, a brake (28) assembles into a movable belt brake roller (28a) and a brake is composed with a movable belt brake roller (28 a) andbrake (28).

In this enforcement either speed sensor (26), a number-of-timesdetection sensor (27) and brake (28) is assembled and divided into threerollers, but a speed sensor (26), a number-of-times detection sensor(27) and a brake (28) are possible to assemble in one roller.

A movable belt driving roller (25 a) is connected to a motor (29), andthe movable belt driving roller (25 a) rolls by the operation of themotor (29), and a movable belt (24) and a foot rest bar (1) move in across direction along with the rolling of the movable belt drivingroller (25 a) and the assistive-passive exercise and a resistiveexercise have been realized as in the first embodiment

A speed sensor (26), which is a parity to a speed sensor (16) of thefirst embodiment, detects the movement speed of a foot rest bar (1) bydetecting a derivation roller (25).

A speed output device (32 b) is a socket that outputs detecting value ofspeed sensor (16) to the outside.

A structure of a serial port for DOS/V is made, but any kind of terminalis good if it is able to detect output value to the outside in thesecond embodiment.

A number-of-times detection sensor (27) detects a number ofreciprocating movements of a foot rest bar (1) by detecting one piece ofmovement of derivation roller (25 b).

A reciprocating motion output device (33 b) is a socket that outputsdetecting value by a number-of-times detection sensor (27) to theoutside.

A structure of a serial port for DOS/V is made, but any kind of terminalis good if it is able to detect output numerical value of the number tothe outside in the second embodiment.

A brake (28) for putting a movable belt (24) brake on and for making itstop is released by the signal from a release switch (34 a).

Therefore, the brake (28) is not canceled, unless release switch (34 a)is operated and the patient is not able to exercise once again.

A speed sensor (26) and also number-of-times detection sensor (27) areconnected to the input side of a control unit (20) through aninformation transmission route (35) and a brake (28), a motor (29) andoutput device (32 b, 33 b) are connected to the output side through aninformation transmission route (35).

Also, an addition resistivity control switch (29 b), a coercive movementspeed setting switch (30 a), a coercive reciprocating motion settingswitch (31 a), a speed setting switch (32 a), a reciprocating motionsetting (33 a) and also a release switch (34 a) are connected to acontrol unit (20).

And, the similar operation is performed, although it is differentbetween the point that the movement of a foot rest bar (1) is carriedout with a movable belt (24), while it is carried out with wheel (9,11)in the first embodiment.

It is not only a training device for effective motivative exercise,assistive-passive exercise and a resistive exercise available as thefirst embodiment, but also the structure to output value for availableresearch, because it is able to detect an exact value about the movementaround a reciprocating movement in a cross direction by using a movablebelt (24) due to the obliqueness line being restricted in connectionwith detection value regarding reciprocating movement.

As mentioned above, lower limb function training device assemblies witha foot rest bar (1), wheels (21) that are composed in the lower surfaceand move and roll toward the right and left, wheel bearings (23 a, 23 b)that accept the wheels (21) in the condition of its movement isavailable toward the right and left and can make a reciprocatingmovement in a cross direction, a speed sensor (26) that detects themovement speed of the wheel bearings (23 a, 23 b) and brake devices thatbrake on the movement in the cross direction of wheel bearings (23 a, 23b) when the mean value of the movement speed of direction, which speedsensor (26) detected or becomes a value of movement smaller than amaximum speed inside a regular interval set.

Therefore, the excessive exercise of a patient can be prevented, in casea patient gets tired due to setting a movement in the cross direction ofa foot rest bar (1) to brake.

And also it can prevent giving the influence of movement in the rightand left direction of a foot rest bar (1), so that a speed sensor (26)is detecting the movement in a cross direction of wheel bearings (23 a,23 b).

As a result, speed sensor (26) can precisely detect the movement speedin a cross direction of wheel bearings (23 a, 23 b) or a foot rest bar(1).

Next, I explain the third embodiment by using FIG. 14 and FIG. 17.

FIG. 14 is a side view of a lower limb function training device of thethird embodiment.

FIG. 15 is a perspective view of FIG. 14.

FIG. 16 is a side view while in use, which sets and fixes the two legs.

FIG. 17 is a side view of the modification of the third embodiment,

(a) is a view of the first modification,

(b) is a view of the 2nd modification.

A foot rest bar (301) is formed of plastic (or can necessarily be madeof wood, etc.) and a space inside with a plane similar to a rectangle.

The foot rest bar (301) has an area of sufficient width that can setboth feet shown as FIG. 16 (for example, the size of the side about 20cm and about 25 cm, length).

Therefore, a disabled person can set both a foot with a disability,which has hemiparesis of lower extremities of a nerve, decline of thelower extremities muscular strength that originates from a plasmotomy ofAchilles' tendon of any lower extremity, a disability in range ofmotion, etc. of an ankle or a knee of any bone fracture etc. and theother healthy foot without any disability in the condition of sitting ona chair, etc.

A heel support part (304) is composed of a foot rest bar (301) as aunit.

It impedes a movement to the rear of the heel of the two feet shown inFIG. 16.

Furthermore, in the case that a foot rest bar (301) is formed of wood,etc., a heel support part (304) can be composed with separated parts.

And also, a setting band (302) that the edge part of the right and leftwas adhered to a foot rest bar (301) is set up both with the intervalfrom this heel support part (304) to the front and approximately thecentral position in the long hand direction of a foot rest bar (301).

A setting band (302) sets through the undersurface of a foot rest bar(301), both end parts of which pass conducive brackets (303), which is aplane Japanese letter (ko) character form, respectively, and whichassemble in each right and left aspect of a foot rest bar (301) and arekept upward of a foot rest bar (301).

And both right and left end parts (302 a) of setting band (302) areoverlapped mutually and are engaged by proper engaging means such as avelvet-fastener, snapshot, hook, etc.

Also, the setting band (302) is composed of one setting band, it is ableto be composed of two setting bands, end parts of which are fixed in afoot rest bar (301).

The setting band (302) is impeding the movement to both feet from theupper and front side shown in FIG. 16.

This securing tools to hold both feet in a foot rest bar (301) as shownFIG. 16 are composed by the heel support part (204) and the setting band(302).

The structure and material etc. of securing tools (302,304) are possibleto change suitably, if both feet can be kept and set on a foot rest bar(301) as shown in FIG. 16.

At the condition that a patient recovered and power of each can be putin to both legs, the securing tools to both legs may be unnecessary.

A load device (305) is composed with the lower part of a foot rest bar(301).

A load device (305) is a material of a spring that can be replaced inthe third embodiment.

Spring material as the elastic body of a load device (305) in the thirdembodiment is a load device, which adapts to a motivative exercise andgives the load repelled by total power (for example, about 20 kg) ofweight of the foot (for example, about 15 kg) and power of applying aload in front of the foot (for example, about 4 kg).

The load, for which about 20 kg is exceeded, in the case ofnon-motivative exercise but a resistive exercise and also muscularstrength exercise especially is sufficient according to a patient'ssituation.

Though a load device of FIG. 14 or FIG. 16 is a compression spring, aload device of FIG. 17( a) is a tensile spring (305 a) and a load deviceof FIG. 17 b is a flexible band (305 b) such as an elastic cord, whichpulls up a foot rest bar (301).

The load device (305) is fixed in three places at a setting concaveportion (301 a), which is composed almost in the center of anundersurface of a foot rest bar (301), by mounting screws (306).

The other side is fixed in three places at a setting concave portion(314) that is composed in the upper part of a mounting convex protrusion(315) of a lower limb function training device cover (310) by mountingscrews (306).

A gradient angle defined supporting device (307) is a cord.

An angle, which is the horizon, of a foot rest bar (301) has a rangefrom 0 degrees of the minimum angle to 37 or 38 degrees of the maximumangle to a desirable angle of a motivative exercise by the gradientangle defined supporting device (307).

And, a foot rest bar (301) becomes possible to move in this range.

The upper part of a gradient angle defined supporting device (307) isglued on a foot rest bar (301).

The lower part of a gradient angle defined supporting device (307) isfixed at the upper part of a mounting convex protrusion (315) of a lowerlimb function training device cover (310) by mounting screws (308) andit becomes easy to fix a load device (305) by mounting screws (306).

A foot rest bar (301) is held with both a brake storage bearing (311)and a bearing part (316) of a lower limb function training device cover(310) to a foot rest bar turn part (309), which is fixed to out side ofa foot rest bar (301) as a unit with the center freely pivoting.

A foot rest bar turn part (309) perforates a brake storage bearing (311)and an accelerometer (312) is assembled at the end of a foot rest barturn part (309).

As well, a lower limb function training device assembles to control unit(320), which is composed of a microcomputer etc, an accelerometer (312)is composed on the input end of the control unit (320) throughinformation transmission route (313) and in the other hand a brake(321), a motor (322) as a drive unit, a display unit (327), an antenna(332) and an output device (326) are composed on the output end of itthrough the information transmission route.

In addition, although an antenna (332) and an output device (326) do notnecessarily need to be included, the detection value etc. of anaccelerometer (312) can be output outside by this antenna (332) andoutput device (326).

An accelerometer (312) detects the acceleration at the time when a footrest bar (301) is trodden downward.

The detected acceleration is transmitted to the control unit (320),which consists of a microcomputer, through the information transmissionroute (313).

In a control unit (320), whenever the signal of acceleration is inputfrom an accelerometer (312), it has counted, and the number of times ofrocking of a foot rest bar (301) is generated.

And a control unit (320) memorizes the acceleration, which is input froman accelerometer (312) and the number of times of rocking of a foot restbar (301) as data in memory department, and outputs it suitably ifneeded.

Moreover, control unit (320) has the acceleration control function, inthe case that the acceleration, which is detected with an accelerometer(312), exceeds the acceleration of a regular standard value that is thesetting value set up beforehand (for example, the maximum accelerationfor every fixed time) or a switch (331) that was the settingacceleration value set up beforehand outputs an alarm signal and makesan alarm device drive.

For example, it can sound a buzzer or flash an indicator display unit(327) and/or transmit data from antenna (332).

With this alarm, a caregiver can change the strength of the load device(305) into optimum setting.

Furthermore, as mentioned above, control unit (320) is counting thenumber of times of rocking of a foot rest bar (301), and outputs a stopsignal to brake (321) when this number of times of rocking of a fixedstandard (for example, about 20 times) or the number, which was set upwith a setting switch (329), is exceeded.

If a stop signal is received, brake (321) brakes a foot rest bar turnpart (309), and will stop rocking.

In the case of the third embodiment, switch (321 a) is operated manuallyand this brake (321) is canceled.

Because it is used with changing a switch, it is a consideration thatpatients do not exercise excessively, continually and easily.

An exercise is impossible again, without releasing a brake.

Although a display unit (327) in the third embodiment is a digitaldisplay screen, as long as it can display of the number of times ofrocking, display of acceleration, warning etc., any kind of displaydevice may be used.

Moreover, any kind of forms is sufficient although an output device(326) in the third embodiment is 10 base T.

Although an antenna (332) outputs the acceleration and the number oftimes, which were inputted and also can set an acceleration, number oftimes of rocking etc. to a control unit (320) with a remote control whenapplying a brake (321).

A battery storage part (323) shows a storage part of a battery.

Moreover, an input part (324) of external electric power is also formed.

A charge method or a non-charging method is also possible for thebattery.

And when a battery is used as a charge method, it is possible to chargefrom an input part (324) of external electric power supply.

Moreover, it is also possible to make a foot rest bar (301) rockcompulsorily by a motor (322).

For example in the case that there are hemiparesis after apoplexy, adecline of muscular strength of the lower extremities is caused by therupture of the Achilles' tendon and/or disabilities of the range ofmotion in ankle originating in a bone fracture of the lower extremities,both feet are set and fixed in a foot rest bar (301) by setting togetherheels of both feet one with a disability and another healthy footwithout any disability to heel support part (304) and attaching foot tipby setting band (302) strapping both feet, fixed in the sitting positionbecause of the third embodiment of lower limb function training deviceassembled as stated (Refer to FIG. 16).

Thus, it is able to set and put on both feet with the upper surface of afoot rest bar (301) corresponding to the size of a disabled person'sfeet easily, because it is good that heels are set and put on to heelsupport part (304), setting band (302) sets and attaches foot tip inorder to set and fix both feet with a foot rest bar (301).

Herewith, the training is done with rocking a foot rest bar (301) in thedirection as shown with the arrow of FIG. 16 by gradually adding powerwhile controlling subjective movement for making lower extremitiesexpansion and contraction, muscular strength of lower extremitiesreinforces and flexion and dorsiflexion of lower extremities byexpanding a range of motion of those due to healthy foot assisting afoot with a disability by not increasing a burden.

The example shown in FIG. 17( a) shows that it is possible not to loadfrom a lower part like the spring material of the load device (305), butto load a way from the upper part by pulling up.

A frame (317) is a frame body that is able to include a lower limbfunction training device and a heel setting part is an opening space andis needed in order to use freely.

Moreover, it is good that security materials (319), which are crossed toboth side covers of frame (317), are sufficient to have the strength toassemble a load device (305 a), for example, about 60 kg in order.

The example shown in FIG. 17( b) is used to install a pillar near heelsand it is possible for a load device (305 b) to be assembled.

Either one or two pillars (318) are sufficient as long as it has theintensity, which does not break, for example, when it pulls by almost 60kg in order that it assembles a load device (305 b).

In the third embodiment, a load device (305), which is a spring, can beany kind of material, which can apply a load such as oil pressure, airpressure and elastic pressure and also has rebounding power.

The effect of such an exercise is connected to the improvement ofdisabilities.

However, disabled persons, who desire to recover as soon as possibleeven one day earlier, exercise many times and then may exceed the rangeof proper quantity and may exercise.

Therefore, the improvement that is expected may not be sometimesobtained.

So that there is no such case, a number that should be exercised to aproper value is regulated by operating a brake (321) with control unit(320).

The number can be set for approximately 10 times minimum to 50 timesmaximum into a control unit (320) by operating a setting switch (329).

And, a control unit (320) causes a brake (321) to be operated, when itbecomes the setting number and suspends rocking of a foot rest bar(301).

I explain the fourth embodiment of a lower limb function training devicein this invention by using FIG. 18 or FIG. 22.

A storage device (503) and a supporting structure (502) are arrangedboth side of said foot rest bar (501) but it is not necessary to keepsaid foot rest bar (501) by the both side.

Although it is not illustrated, holding only at one side is alsopossible.

Magnets are used for a set up structure (506) of the foot rest bar to acase (505).

When said foot rest bar (501) is tied to a case with a string, onlynecessary is to anchor a string to the case (505) by hooking on or anyothers.

The Dorsi-Plantar Flexion exercise of ankle is shown in FIG. 20.

The stretching exercise of legs are shown FIGS. 21 and 22

In this embodiment, it is possible not to use a case but to attach thisinvention to chair directly.

Moreover, not only own chair but a chair ahead can be attached and useby the person sitting a next chair.

And there is a case where a lower limb function training deviceassembles load devices (507), which weights a load to a reciprocatingmovement in the cross direction of pivot axis.

A load device (507) which detects the number of times of reciprocatingmotion of pivot accis of the foot rest bar (501) assembles, which theround trip movement, based on pendulum motion, number detection devicesdetected, reaches a set value of times.

Moreover, there is a case that a drive device is set in said storagedevice (503) or another arrangement.

Moreover, there is a case that A number sensing device is set in saidload device (507) and/or said storage device (503).

And then there is a case when a brake device including in said loaddevice (507) and/or set to the pivot axis brakes a foot rest bar of areciprocating movement in the cross direction if the average value ofthe movement speed in the cross direction of the foot rest bar requiresmore time to perform.

And there is a case where a number detection devices on a said pivotaxis which detects the number of times of reciprocating motion in across direction of the foot rest bar assembles, which the round tripmovement.

Said number detection devices detect a value of times and reaching a setvalue of times.

Although the lower limb exercise equipment is placed inside the storagedevice in this practical example, it can be placed outside.

Also, though the details are skipped, it can be attached directly to achair or a desk without the storage device. For its use, plantar anddorsal flexion exercises of ankles are carried out if heels are put onthe floor.

If feet are put on the foot rest bar with their heels free, flexing andextending exercises of knees and bending and stretching exercises offeet are carried out.

And, there is a case that a foot rest bar, both the feet or one foot arekept on is available to perform alternatively, a reciprocating motion inthe cross direction or to rock in the vertical direction.

The feet move as focusing on the heel that put on the floor with thefeet.

Also, there is a case that a foot rest bar, which both feet are kept onis available to perform alternatively, a reciprocating motion in a crossdirection with no feet on the floor.

A foot or feet on said foot rest bar is available to rock in a verticaldirection on own heel put on the floor for pivot axis.

Furthermore, there is a case that a round trip movement, based onpendulum motion, number sensing device in the that detects a number ofreciprocating motions by the sensor set in said supporting structure(502) and/or said storage device (503)

Therefore, it can be prevented that users exercise more than a set valueof the number of times of a reciprocating motion. Consequently,preventing the excessive exercise of any user can be possible.

Any user can do an exercise freely by setting number of one's intentionin the case the foot rest bar is a round trip movement.

An exercise that adds a load is available, in the case that the lowerlimb function training device is equipped with a load device that adds aload on the movement of a cross direction.

Consequently, excessive exercise of a patient can be prevented.

The example of change of this invention is illustrated below.

(1) In the embodiments mentioned above, although the speed of a footrest bar is set up by the average value for every fixed interval (forexample, during the movement of a foot rest bar forward and every fixedtime), it is also possible to compose a brake device which appliesbrakes if the highest speed for every fixed interval of order movementor rocking becomes below set value.

If the average value of the movement of reciprocating in the crossdirection or the rocking of the foot rest bar requires more time toperform, it is good for setting up a brake device that brakes in thecross direction movement or the rocking movement of a foot rest bar, forexample, it is also possible to operate a brake when a value of theacceleration becomes smaller than a regular interval set instead of aspeed.

Furthermore, it is also possible to apply brakes at the rocking speed ofa foot rest bar.

And a rocking speed for applying brakes is set up by the average valuefor every fixed interval (for example, in every fixed time and under amovement of a foot rest bar to the lower part).

(2) A moveable structure of foot rest bar (1) for a cross direction canbe changed suitably.

For example, arrangement and the quantity of wheels can be changedsuitably.

However, in order to stabilize a foot rest bar, it is desirable toarrange wheels to the front and rear, right and left of the lower partof a foot rest bar.

(3) An output from an external output unit is possible also by acommunication cable or a memory medium.

(4) A load device, which adds a load in the cross direction movement ofa foot rest bar (1), can be any structure other than motors (19, 29).For example, it is possible also with a device, which adds frictionresistance to a wheel or a movable belt.

(5) A structure and a form of a speed sensor can be suitably changed, ifthe speed of a foot rest bar (1), especially if the speed of the frontare detectable.

For example, it is also possible to detect a speed of a foot rest bar(1) indirectly.

Moreover, the number of times of a reciprocating motion of a foot restbar can also be calculated by the number of times of change in thedirection of speed, which has detected a speed sensor.

In this case, a speed sensor serves as the function of a number-of-timesdetection sensor.

(6) Warning devices such as a buzzer and a lamp are assembled and whenmaking a brake device operate in case that the number of times and thespeed of a reciprocating motion of a feet setter become a set value, itis also possible to operate this warning device.

(7) It is also possible to form drive equipment, such as a motor, whichmakes a foot rest bar rock.

POSSIBILITY ON INDUSTRY USAGE

This invention is effective when motivative exercise is done for bothfeet, in the case that there is a disability as a result of hemiparesisafter apoplexy, a decline of muscular strength by the rupture of theAchilles' tendon and disabilities of the range of motion in the joint ofa leg or knee originating in a bone fracture in one leg, which is thefoot with a disability and another healthy foot without any disability,in the sitting position on a chair.

It is an effective training machine, which realizes movements of both across direction and vertical direction.

So as to perform a motivative exercise of a disabled lower extremity bya healthy lower extremity, heretofore lower extremities functiontraining devices, which were divided into each training device thatcould only perform in a cross direction movement or in a verticaldirection movement; two kinds of the devices could be summarized to onemachine in order to make it positively usable in a narrow house.

In this way, it is easy to treat and data is outputted outside, itbecomes easy to perform a medical checkup or to change a training menuby remote control.

Moreover, in order to know a patient's condition conventionally, aphysical therapist measured the angle of extremities with a contractureand has measured the patient's body situation.

Therefore, the physical therapist and a patient must be in the sameplace to perform needed measurement.

In this fourth embodiment, telemetry becomes possible because of themeasurement of the angle of the lower extremities, which has acontracture becomes possible by the relation of feet and legs of fourpoints contacting simultaneously.

At once to eliminate the ambiguity by viewing becomes available.

And a brake device brakes on a foot rest bar and can suspend an exercisein the case that a patient gets tired and the movement of a foot restbar becomes slow; in the case of a brake device braking in a crossdirection of a foot rest bar at the time of a reciprocating motion in across direction movement of a foot rest bar needs a longer time.

Consequently, too much movement of a patient can be prevented.

And a brake device brakes on a foot rest bar and can suspend an exercisein the case that a patient gets tired and the movement of a foot restbar becomes slow; in the case of a brake device braking in a crossdirection of a foot rest bar at the time of a reciprocating motion in across direction movement of a foot rest bar support axis needs a longertime.

Consequently, too much movement of a patient can be prevented.

And a foot rest bar is manually moved by a physical therapist, detectionof the feet with contracture occurs by touching the four points of afoot rest bar and it is possible to automate detection of an angle oflower extremities with contracture namely the grade of contracture byoutputting the angle.

Data for a research and a management of the momentum of a patient can beobtained easily, in the case that a lower limb function training deviceis outputting at least single detected data by a round-trip movementnumber sensing device and a movement speed detection device in theoutside.

The invention is used to solve the subjects mentioned above and to aimat offering a lower limb function training device, which can preventthrombophlebitis known as economy syndrome.

And it is the secondary purpose to offer a lower limb function trainingdevice, which can perform two kinds of exercises.

And also, it aims to offer a lower limb function training device, whichcan motivate people to exercise and enables exercise two kind ofmovement.

There is no report that economy syndrome went out even if airlines haveintroduced the exercise by stretching legs and the Dorsi-Plantar Flexionexercise with no equipment.

A lower limb function training device provides two kinds of exercises.

One is a Dorsi-Plantar Flexion exercise device and the other is astretch exercise.

People can use it as a Dorsi-Plantar Flexion exercise device by puttingtoes on the device with heels on the ground surface and can do abilateral movement in one time training.

People can use it as a stretch exercise device by putting sole of feetand/or heels on the device not to touch those the ground surface and cando a bilateral movement in one time training.

If the symptoms progress, it may become pale by compression of arterialblood flow.

Also, it may cause thrombophlebitis of lower limb.

Moreover, if thrombus which caused this venous inflammation lodges inpulmonary artery, it may lead the sudden death because of the pulmonaryembolism.

The news that a Japanese famous soccer player was hospitalized becauseof the pulmonary embolism and the venous inflammation is well known. Hereceived a medical treatment to dislodge the thrombus by administrationof anticoagulant drugs.

This invention, training with the device, enables to give stimulus thatcould not be obtained from the exercise with no device and improves theflow of the vein even if it is obliged to keep seated for long time.

Moreover, this will prevent and avoid the risks mentioned above.
